Yaaaaay doom I finally get to play brutal doom

Amazing

Its good but i have one issue

Make a option to disable dragging for all buttons because when im trying to select options and stuff the A button can press multiple times from one push and makes things tedious

Audio stopped working

Works great for a while then I bought the full version and the audio died.

Touchscreen and Gyro need improvement

Best way to play Doom on iOS but it does have an issue with the touchscreen and gyro aim, you can't make micro adjustments in your aim like there's a deadzone and changing both the sensitivity in the settings and gzdoom settings messes with it. If you max out the settings sensitivity and use it as a base for the gzdoom sensitivity it makes the deadzone smaller but it's still present and feels bad to the point I can only play with freelook turned off. Im sure most people play with a controller so it's not huge issue but for people that come from other mobile games like COD Mobile or Delta Force Mobile and know how to play well with the touchscreen and gyro it doesn't feel great. Hopefully the Devs see this and can improve the touchscreen and gyro controls.
